SCALE.

- To all whom itmay concern:

Be it known that I ALLEN DE VILBIss,

i Jr., residing at Toledo, Lucas county, Ohio,

have invented certain new and useful Improvements 1n Scales, of wh ch the following is a specification.

My invention relatesto that kind of scale known asa computmg scale, by which are indicated both the weight and the value of an article at any givenpric'e per pound or other imit of weight.

This invention has particular applicability to the pendulum'type of computing scale, in which a removable pendulum weight is provided in. addition to the usual fixed or permanent weight, for the purpose of increasing the weighing capacity and t-he price-computing range of the scalein 'the manner fully described in my prior patent, Reissue No. 12,029, dated Septemher 9, 1902.

The'object of my present invention is to provide mechanism under the control ofthe operator or salesman for applying such removable weight to thependulum and de- -positing the same properly in place upon the fixed weight, with the result that the scale' in its increased capacity, will indi-- cate both weight and price with absolute 3O accuracy.

I also provlde novel and efiicient means for indicating to the operator the fact whether the removable we1gh t 1s 1n operative or inoperative condition and also what particular weight and price figures to read, whether the red or black ones according to the selected distinguishing colors adopted.

; The various features of advantage and 'utility in my novelmechanism will be understood from the descriptlon hereinafter Specifieationof Letters Patent.

Application filed December 26, 1903. Serial No. 186,686.

similar to Fig. 1 but with the removable weight deposited on the fixed weight in position to cooperate with the pendulum to increase the weighing and price computing capacity of thescale; Fig. 7 a bottom plan view of the removable weight; Fig. 8 a top plan view of the fixed or permanent weight; and Fig. 9 a detail viewshowing the relative positions of the two weights when the removable weight is in inoperative condition.

My present scale is a computing scale of the general type and operation ofthat illustrated in my patent aforesaid, by which both the weight and the value of the article at any given price per pound or other unit of weight are indicated.

As in my prior scale, I employ a price .computing table or chart having a plurality of rows of price totals and also having a plurality of rows of weight units, of which the numbers in one row are multiples of those inthe other. with all of which rows there cooperates an index having a plurality of rows of price units arranged side by side and having correspondingly arranged numbers in the several rows 00''. operating with the same'rows' of price totals. The computing table and index are movable relatively to each other under the influence of the load upon the scale platform. such load-being counterbalanced by a weighted pendulum which affords the necessary resistance to such relative movement. In order that the different series of rows of weight units on the table and of the price units on the index may be distinguished and thereby easily read. I prefer to make or print them of contrasting colors, as in the present instance blaclnandred, although any other colors or other'me'ans of distinguishing may be adopted. As herein shown. the scale is so constructed as to afford to the customer an indication ofthe weight only and to the salesman'an indication of both the weight and price or'value ofthe article.

In the present instance, as in my said prior patent, a supplemental weight is adapted to be applied to the pendulum for the purpose of increasing the resistance offered thereby to the relative movement of the indcx and computing table, with the result that the capacity and range of the scale are increased according to the weight of such supplemental weight so applied. In the present scale herein shown and described the weight is such as to double the resistance of the pendulum and thereby double'the capacity of the scale. said prior patent the supplemental weight was applied to the pendulum and removed therefrom'directly by the hand of the operator or salesman.

The object of my present invention is to provide simple and efiicient mechanism under the control of the salesman whereby such transfer and removal of the weight may be effected, and also to provide visual signals or indicators for indicating to the customer and salesman whether the supplemental weight is in effective relation with the pendulum or not and accordingly which particular rows of numbers are to be read, the black or the red, if such are the contrasting colors adopted. By this mechanism the supplemental weight is positively and accurately placed in position on-the pendulum, that is, superimposed on the usual fixed or permanent weight of the pendulum, as will be made apparent from the detailed description now to be given.

As herein shown, my present scale has a base 1, supporting a casing or housing 2 for the computing table of the scale as well as for the working parts controlled by the usual scale beam 3. This beam projects into the casing and its hook-shaped inner end is connected by a link 4 to the disk 5 of a pendulum 6, which has at its lower end a fixed or permanent weight 7. By-preference, I. provide a stop or buffer 7 to check the return movement of the pendulum 7 which stop or buffer'is made of any material suitable for the purpose, such-as rubber, and support the same on a post 1, rising from 'the top surface of the base portion 1 of the scale, Fig. 1. The index hand 8 is secured to the disk and projects upwardly there from at an angle to the pendulum. This index hand is bifurcated soas to cotiperate with both sides of the table or chart, which in the present instance and as usual is pro-- vided on the salesmans side with both the weight and price indications and on the pun chasers side with the weight indications only. The chart 9'on the salesmans side is exposed through the open or transparent front of the casing and on the purchasers side through the slot or sight opening 10 in the casing. The weight indications are shown at the upper end'of the table or chart and the figures are arranged in two parallel rows, which rows of figures are by preference distinguished from each other by dif- In myferent colors, as for instance the lower row may be black and the upper row red. In the present instance the weighin' capacity of scale is 10 pounds when the alone is used and 20 o'unds when the removable weight, hereinafter described, is

xed weight 7 i used, and consequently the lower row of;

weight figures reads from 1 to 10 and the upper row from 1 to 20, as shown in Figs; 1,

2 and 3.

The scale so far described is substantially the same scale as that of my rior patent in which the removable weig t, commonly called a ball, was laced on the pendulum and removed there mm by hand when desired. To enable the operator to 50 place and remove the weight in an expeditious manner and withoht in fact handling the same and in order also to place such weight' in accurate position are the objects of the additional parts or mechanism now to be described.

By means of pins 11 a carrier frame is pivoted within the casing or housing of the scale and so constructed as to carry or support the removable weight 12 when not required, and to deposit it in operative position on the pendulum when required to increase the capacity of the scale. This frame comprises the cross-bar 13 and the two substantially parallel projecting arms 14 and 15 which extend along opposite sidesof the pendulum when in normal position. These arms are provided with upwardly projecting lugs 16 which engage in vertical slots or recesses 17 in opposite sides of the removable weight 12, so that the proper position of such weight on its carrier is always assured and maintained.

The cross bar 13 of the carrier provided in suitable manner with an arm or lug 13 which extends at an angle thereto and cooperates with a cam 18 secured to' or formed as a part of a rock shaft 19. v This shaft extends transversely of the casing and bears in opposite walls thereof as seen in frame is Fig. one end thereof extending through the casing and being there provided with a finger piece 20 wherebv the operator is enabled to rock the shaft as desired. An indicator or pointer 21, operated bv such rock shaft, is employed to point either to" the word Red or Black. to indicate whether the red or the black figures on the table or chart are to be read. The rock shaft is also provided with a segment 22 formed separate from or integral with such shaft and arranged to be swung in the samcvcrtical plane'as the scale beam, with the result that when swung to a vertical position in the manner illustratcd in Fig. 6 the scale beam, if previously in lowered position at this end, will be positively raised and tho pendulum thereby restored to normal vertical position. The purpose of this'arrange' ment is to bring the pendulum to proper position before the removable weight or 'ball is placed or deposited on the fixed weight,

or at least to assure such pendulum being in such position. v

The arm 14 of the carrier frame is ex tended beyond the other arnr and pivotally' connected to a long link or rod 23, whose up- 791' end is pivoted eccentrically on a thin disk 24. This disk is pivoted at 25 to one wall of the scale casing and is provided on. the customer's side with suitable signs or indications notifying the customer whether the red or black figures are to be used in reading the weight. In the present instance I have marked on this indicating disk the sets of'words Read red figures and Read black figures so arranged that one or the,

other set will be exposed to the customer through the sight opening 26 according to the position of the rock shaft and corresponding to the indication by the pointer 21.

sequently, the removable weight is now in inoperative condition but ready to be de posited "and attached to the fixed weight. At this time. the pointer 21. as well as the disk 24. indicate that the black figures at i to be read. In order to deposit the removable weight or ball inplace on the fixed weight. -the operator. by manipulating the The removable weight is thereby deposited finger piece 20. rocks the shaft 19 in an. anti clockwise direction with the result thatthe segment 22 and cam 19 are rocked in the same direction. the scale beam brought to or maintained in normal position with the pendulum in vertical position. and the carrier frame lowered. all as illustrated in Fig. 6.

on the fixed weight, whose projecting pins 28 are received by the corresponding holes 2) in the under face of the removable ball or weight. The carrier frame when swung downwardly as just described entirely clears the removableweight or ball. leaving the latter in place on thefixed weight.

'For the purpose of holding the pendulum to an accurate vertical position in order that the removable weight may bedeposited with precision. I employ a bail 30, whose parallel arms are pivoted at 31 to opposite walls of the scale casing. To one of these arms is pivoted the upper end of a link or rod 32. whose lower end is provided with or formed as an eccentric-strap 33cembracing an cccentric 31- on the rock shaft 19. lhe con struction is such that when the shaft is rocked one half .of its fulldistance of movement", as shown. in Fig. 6; or substantially so, the bail 30 is swung to its lowermost or effective position to maintain'the pendulum in exactly vertical position. 'Upon furthen'iO rocking of the shaft to the left the eccentric swings the bailupwardly to the same horizontal position originally occupied by it. The object of this arrangement is to remove the bail. after performing its functions, out "/5 of the range of the pendulum.

At thistime the pointer 21 and disk 24 indicatethat the red figures are to be used in reading the table or chart. 'hen the shaft 19 has been rocked half way the carrier frame has been swung substantially to its lowermost limit, as seen in Fig. 6 and the continued rocking of the shaft to the left has no effect upon the carrier, the only effect heing'to swing the bail upwardly and the segment 22 downwardly out of range of the scale beam.

T 0 remove the weight 12 the shaft 19 is rocked in a clockwise direction, whereupon the carrier frame is swung upwardly and the weight 12 thereby removed from the tixed weight. the movements of the parts being'thereverse of those already. described. It will be understood that the salesmans side of the chart or table exhibits a plurality of rows of price totals but inasmuch as the same foriu no part of my present invention and moreover are difiicult to illustrate, I have shown only the two uppermost rows thereof, leaving the remainder of the chart or table blank. only a few of the price units on the index 8.
